Re: [R] issue in running timeseries forecasting related package

Hi It is weird. Maybe others could come with some sensible answer. I would try to start R with -vanilla switch Rgui.exe --vanilla and try if everything is OK. If yes, you could start loading packages and see how all is working. If not I think that the only option is reinstaling R and packges

[R] repeated measures: multiple comparisons with pairwise.t.test and multcomp disagree

Hi, I am working on a problem which I think can be handled as a repeated measures analysis, and I have read many tutorials about how to do this with R. This part goes well, but I get stuck with the multiple comparisons I'd like to run afterward. I tried two methods that I have seen in my readin

You could apply na.omit() to just the columns you are using: > dcast(na.omit(df[,1:2]), v1 ~ v2, length, margins = TRUE) Using v2 as value column: use value.var to override. v1 X Y Z (all) 1 A 1 2 2 5 2 B 1 2 1 4 3 (all) 2 4 3 9 - Davi

Mike, There may be a more efficient way to do this, but this works on your example. # mix up the order of the rows mix <- dat[order(runif(dim(dat)[1])), ] # get rid of duplicate x1s and x2s sub <- mix[!duplicated(mix[, "x1"]) & !duplicated(mix[, "x2"]), ] sub Jean On Mon, Jun 22, 2015 at 11:42

I'm using the "dcast" function from Hadley's "reshape2" package to do some tabulations. I can't get it to exclude NA's in the variables being tabulated. Here's a simple example. v1 <- c(rep("A", 5), rep("B", 5), NA) v2 <- c("X", "Y", "Y", "Z", "Z", "X", "Y", "Y", "Z", NA, "Z") v3 <- c(rep("a", 4)
